Hello Viewers, in this video, a scheme is presented to detect QRS complex (R-Peaks) of an ECG signal using undecimated Discrete Wavelet Transform (DWT). It is shown that how band pass filtering of ECG signal is achieved to preserve R-peaks using DWT which is superior than frequency selective BPF. Also by counting total number of R-peaks are counted Heart Rate (in beats per minute) is also calculated. Also robustness of the proposed scheme is shown on different types of ECG signals taken from MIT-BIH arrhythmias and ECG-ID databases from PhysioNet.
